[chicken]

just re-read my original message and it may give the wrong impression.

I am not trying to imply that the garage or its staff stole parts off my car. The garage is not disputing that a crime took place (the police came to investigate) but they are saying they are not liable for the damage because they have signs up to that effect.

I'm getting a lot of comments saying that the garage is/should be liable but it would be handy to have a comment from someone with a legal background.
